This invention relates to a vaporizer and supercharger for internal combustion engines, the general object of the invention] being to provide means for heating and thoroughly vaporizing the explosive mixture as it passes from the carbureters to the cylinders so as to greatly increase the efficiency of the engine by increasing the combustibility of the charge, increasing the miles per gallon, preventing overheating and 'carbonization of the engine and Otherwise securing Y combination and arrangement of the several parts, to be hereinafter fully described, illus T coupling in the exhaust pipe.

trated in the accompanying drawings and specifically pointed out in the appended claim. Indescribing the invention in detail, reference will be had to the accompanying drawings wherein like characters denote like or corresponding parts throughout the several views, and'in which Figure 1 is an elevation of amotor, showing the invention in use thereon.

PATE T LOUIS M. FABBRO, or CLEVELAND, OHIO, Assrsnoa, BY D nner nun Muslin Ass1 riv inner face, theseshoulders forming seats for i the. inner cylinder 5. which is of considerably less diameter than the outer cylinder so that the cylinders form an annular chamber 6 between them. Each end member is formed;

with a frusto-conical recess 7 inits inner face, these recesses forming continuations of the space formed by the Inner cylinder andthe front end member'is formedwith' a 'passage 8'which' communicates withthe. recess 7 of said end member and whichis connected by the pipe 9 with a carbureter 10. Asiinil'ar passage 11 is'formed in the" rear end member and this passage is connectedby a pipe 12 with the intake manifold 13 of the motor, A passage 14 is formed in each of the end members 3 and these passages communicate with the annular space 6 and a pipe 15 connects the passage 14 in the frontend memher with a T coupling 16 which is connected with the exhaust manifold 17 and the exhaust pipe 18 of the motor. A pipe 19 connects the passage 14 in the rear end member with the exhaust pipe 18. I

A shaft 20 passes through the front end member and-has its rear end fitting in a bearingrecess 21 formed in the hub of a spider 22 located in the rear end of the inner cylinder 5,'a small'tube 2.3 extending through the rear member to the recess so that lubricant placed in a cup' 24 on the outer end ofthe tube will pass to the bearing recessand thus lubricate the parts. Thefront end of'the shaft is provided with a pulley 25 over which a belt 26 passes, thisbelt also passing over a pulley 27 on the shaft of the fan 28 of the motor. Thus the shaft-2O will'be driven by the motor.

Spiders 29 are carriedby theshaft'20 and are located within the inner cylinderfi and a cylinder 30 of foraminous material is attached to" said spiders so that this cylinder will rotate with the shaft A fan 31 is attached to the shaft 20 andjhas its periphery connected with the cylinder 30,.thisfan being ing also formed of 'for aminou s "material.

The "baffles 33, also formed of 'foraminous material, are connected with the shaft and cylinder and are arranged between the convolutions of the spirals. Thus the cylinder 30, the'two spirals 32, the battles 3.3 and the fan '31 rallrotate within the inner cylinder 5.

From the foregoing it will be seen that the mixture fromthe carbureter enters-thefront recess 7-through the passage 8 and'thenenters the inner cylinder 5, where it-isacted-on by the spirals, the bafiles and the fan so that the mixture leaves the cylinder 5 in the form of a mistandthis mist passes through the pipe 12 into the inlet manifold 13, from which it passes to the cylinders of the motor. The :exhaust gases pass through a the pipe 12 .into the 'front passage 14 and after circulating around'the inner cylinder in the space6, the exhaustgases pass through the rearpassage 14 into pipe 19, from which they pass into the-exhaust pipe. Thus these .hot gases will highly heat the explosive .mixture passing through the inner cylinder '5 so that they are vaporized at the same timethey. are'being .acted on by the spirals, baflies and fan 31, so that themixture-enters the cylinders in a highly combustible state.

A valve 34 is arrangedto controlthe flow I [of exhaustgases into the pipe 15 and the arm ot thisvalve is connected by a link 35 "WlthIIHflImISG which .is pivoted in thecasing 37 ofathermostatic device, the inner end, of the arm ihaving a toothed segment 38 thereon which engages a gear39 rotatably arranged in thecasing 3'? and which isacted .oniby atoothed partdO attached totheupper end of athermostatic member ll, the lower end of which is connected to tthe;lower.end of a tube 42 into which the member rlpasses, thistube extending into the spacezG. between the innerand outer cylinders, e38 shown in Figures 1 and 3. Thus-thethermostatic.device isactedon bysthehot exhaust gasespassing through said spacewand the-movement of .the thermostatic member will control the damper or valve 8Landthus the fiowof exhaust gasesithroughlthe space 6 will be automatically controlled. As shown, when the thermostaticinember is in neutral position, the damper will closethe exhaust pipe 18 so that allthe exhaust gases will passpthrough the pipe 15 into the space -6, but when the thermostatic member is ,fully expanded, the

damper will close thecommunicationbetween .the pipe15 and the coupling l6.so thatnone ofthe gases will ,pass through the :device. The gear 39 also operates the finger .48 pivoted in the casing .37 and operating-over the scale 42 for indicating the .-teinperature .of .theexhaust, gasespassing through the device.

Thus I have provided means :forthorough- I I 1y vaporizing and commingling the explosive mixture. as it passes from the carbureterto the ;'In0t0r, the mixture being :heated by the exhaust, gases :from themotor and theitemperacomprising inneinaiid outer cylindersspaced 7 ofpassagcs, onepassage bein gin communicaof fuel.

It is thought from=the foregoing description that the advantages andnovel features of the invention will be readily apparent.

It'is'tobeunderstood-that changes may be made in the construction and in the combination and arrangement of the several parts,

provided.thatsuch changes fall within the scope otthe appended claim.

, What I claim is A mixing devicerfor-an explosive mixture,

apart to forniaii annular chamber,endplates yclosing'zthe ends ofthecylinders, each plate beingfornied with. acentral recess forming a continuation of theinner c'ylinderand apair tion with the.annularchamber and the other 'withthe recess, whereby exhaust. gases can be passed through the annular chamber. and exshaftprassingthrough one of the end plates, bearing means tor the other end ofthe shaft arranged in the inner cylinder, a Tan'con- .iiected with the shaft and with the cylindrical'screemhaflles off'foraminous material 00 1- nected with the s'haft and cylindrical screen,
